By reason of this formation, the cap plate snugly telescopes over the head portion of the joint bar, but the it between these parts is sulliciently free or loose so that the cap plate is capable of an independent movement longitudinally, and this movement can be facilitated by the application of 1ubricants between the parts before or during assembly.

It will be observed that the outer and inner lateralV flanges 8 and 9 have an engagement upon the outer and inner faces of the head portion of the joint bar and thereby lretain the cap plate from outward or inward relative displacement with reference to the joint bar, while at the saine i time not interfering with the independent longitudinal movement thereof. With reference to the independent longitudinal movement of the cap plate, an excessive or unnecessary movement in such direction may be prevented by any suitable restraining means, such for instance as the expedient shown in the dra-Wings, the saine consisting in forming the cap plate at its ends with i bent-down terminal retaining lips 10 which are disposed beyond the ends of the joint bar. Suilicient clearance is' provided between the terminal retaining lips 10 and thev adjacent ends of the joint bar toallow for the extent of longitudinal movement requisite for the accom lisliment of the objects of the invention, w ile at the same time preventing an excessive movement of the chafing guard or cap plate in a longitudinal direction.

A further feature of practical importance in constructing Ia chafingguard in the form of a Vmetal cap plate which yconforms to the contour of the headeof a joint bar, resides in the fact that by reason of such complementary relation between such plate and the joint bar head, the, adjacent surfaces of these parts are maintained smooth and' clean through the rubbing movement thereof, and thel maintenance of this 'condition in turn permits and facilitates the relative movecombination, a rail, a joint bai', insulation between tlie'joint bar and rail head, a nietal chang guard consisting of a cap having a web interposed between the insulation and the head of the joint bar, and outer and inner lateral depending flanges engaging over theouter and inner corner portions of the head of the joint bar.

2. An insulated iail joint including, in combination, a rail, a joint bar, insulation -between the joint bar and rail head, and a metal cap plate 'litting plie head of the jointI bar and provided with lateral terminal retaining projections.'

3. An insulated rail joint including, 1n combination, a rail, a joint bar, insulation between the joint bar and rail head, and

a metal cap plate loosely fitting the head of the joint bai' and of greater length than the latter, said cap plate having terminal retaining means.

4. An insulated rail joint including, in combination, a rail, a joint bar, and a nietal plate fitting the head ol the joint liar and having independent longitudinal but not lateral movement therewith, and insulation between the metal plate and the rail head.
